Is a Thermostat Replacement in Your Future? 

Thermostats are an important part of your home’s infrastructure that you may not think much of until they experience an issue. Often, older thermostats are working past their estimated lifespan, and that is when they begin to show signs they may warrant a replacement. 

No matter the age of your thermostat, look out for: 

  • Inaccurate Readings: The device displays a temperature that doesn’t match the actual air in the room.
  • Unresponsive Interface: The screen stays blank or buttons fail to trigger the air conditioner.
  • Short Cycling: Your HVAC system turns on and off too frequently due to faulty sensor data.
  • High Energy Bills: An outdated controller causes your unit to run longer than necessary.
  • Obsolete Technology: Older manual sliders lack the precision of modern digital controls.

We sync your controls with your heating and cooling hardware to ensure every signal reaches your unit instantly.

We diagnose communication issues between the thermostat and the HVAC control board. Our technicians identify loose wiring and replace faulty internal components to get your system back online. If a repair is not cost-effective, we provide clear options for a modern upgrade.

April 21, 2026: Well, R.S. Andrews came to my rescue again. This time I needed the water supply lines to 2 of my toilets replaced as per my homeowners insurance company. Loren, the RS Andrews plumber, was able to replace both lines with only a slight hiccup in one of the lines. He did an excellent job and detailed everything in my receipt so that I could forward my receipt to the insurance company. Loren was awesome. Thank you RS Andrews for saving the day….again. February 2026: Will Macon was totally awesome! I’m a caregiver for my 89 year old mother who just came out of the hospital on Sunday. Our furnace went out on Tuesday. I called R. S. Andrews on Tuesday. Will was at our home on Wednesday morning. He examined our system and got us a GREAT DEAL on a new furnace and AC. It was awesome. The new system was installed on Thursday. By Thursday afternoon we had heat from a NEW FURNACE. Thank you Will and thank you R. S. Andrews for all that you do. You may have saved a life. Thank you!!!! Alane L. Sullivan

After having a couple other companies look at our plumbing and tell us they "couldn't" fix our problem (we have a mixture of stainless steel & cooper pipes; virtually unheard of for residential!), we tried R.S. Andrews. Their attitude from the start was "How can we help" and they found a solution! Not only did they solve that problem, but we've used them for all plumbing and HVAC needs since because the folks provide great service at a fair price!

All the Techs that R S Andrews has sent were very courteous and professional. All details for the repairs were explained along with any follow up visits. Any costs were explained before the Techs came out. I would recommend R S Andrews to anyone who needs home repair.

Brian Turner, technician, and his assistant did an excellent job of diagnosing a gas leak at my water heater and redesigning a more efficient setup and replacing the water heater. It was a huge all day job and they worked tirelessly to make sure things were improved and safe. He was excellent at explaining every step and the reason for the changes. He also repaired other small issues in tub and outdoor faucets.
